    Turns a COORD object into a c_long.
    This will cause it to be passed by value instead of by reference. (That is what I think at least.)

    When runing ``ptipython`` is run (only with IPython), we often got the following error::

         Error in 'SetConsoleCursorPosition'.
         ArgumentError("argument 2: <class 'TypeError'>: wrong type",)
     argument 2: <class 'TypeError'>: wrong type

    It was solved by turning ``COORD`` parameters into a ``c_long`` like this.

#: If True: write the output of the renderer also to the following file. This
#: is very useful for debugging. (e.g.: to see that we don't write more bytes
#: than required.)
